抽放用水压式封孔器FKSW-63/4、73/4型

一、概述 overview

    1、适用范围 Product application  

    FKSW-63/4、73/4型矿用封孔器用于煤层顶底板巷道提前抽放瓦斯,临时封孔的措施。

    FKSW-63/4, FKSW-73/4 hydraulic pressure type hole sealing device for gas drainage is gas drainage and hole sealing device used under coal well self developed by our company; it is applied to drain gas before coal mining, reduce the gas volume and pressure in coal seam, which is mainly used for gas drainage hole, and use water pressure to expand the rubber and to realize hole sealing.

    2、产品特点、结构Product characteristics

    操作简单,使用快速、方便、安全、可靠,并且可以反复使用多次,是煤层抽放瓦斯的理想设备,它由抽放芯管、高压橡胶膨胀管和控制阀门构成。

    It’s easy and convenient to use, safe and reliable, which can be used for many times; it is the ideal equipment used in gas drainage in coal seam.

二、工作原理及使用方法Method of application

    将封孔器的高压膨胀管的接头与井下静压水和高压水连接,封孔器插入需抽放的煤层孔内,打开水阀,当封孔水压达到1Mpa以上时,封孔器的胶管膨胀后把孔封住,而后通过抽放芯管由抽放泵站进行抽排,抽放完毕后打开水阀,可将管内水放出,封孔器即可恢复原状,然后将封孔器抽出,完成抽放工作。

    Connect the high pressure expansion pipe of hole sealing device to the static pressure water or high pressure water, and insert hole sealing device into the coal seam to be drained; open the water valve till the hole sealing water pressure is over 1MPa, and the rubber pipe of hole sealing device will expand to seal the hole, and carry on drainage through drainage core pipe from the drainage pump; open the water valve when drainage is finished to let the water in pipe out, and the hole sealing device will get back to its shape; take out the hole sealing device, and drainage work is finished.
